The draft PIR is submitted to both the HQ and District Pavement Program Advisors for comments. Also, PIRs that have been approved for 2 years should be re-evaluated before delivery to validate the proposed pavement repair strategy. The re-evaluation should consider the latest automated pavement condition survey (APCS) data and include a new Scoping Team Field Review.
Propose a Revision to the HDM
Formal Life Cycle Cost Analysis (LCCA) according to the Life Cycle Cost Analysis Procedures Manual is not required for minor pavement rehabilitation (CAPM) projects. However, some cost analysis is required to support effective pavement management decisions, such as analyzing the cost effectiveness of minor (CAPM) versus major pavement rehabilitation (2R or 3R). A comparison of different pavement products or strategies should be done to support project scoping and life cycle planning during the preparation of the PIR.
Caltrans Policies
Additionally, State law and policies have amended the process for management and selection of State Highway Operation and Protection Program (SHOPP) projects for Caltrans. Minor pavement rehabilitation (CAPM) projects are not intended to change existing geometric features. However, added assets and features as described in Section 4.0 may necessitate the documentation of nonstandard features. The delegated holder of design standard exception approvals must be consulted if the project proposes to create deviations from geometric design standards. Typically, these exceptions include items such as reduced shoulder width due to installation of standard dike, guardrail or bridge approach rail, and increased shoulder cross slope where it conforms to the existing curb and gutter.

Field reviews should be scheduled to encompass as many different project locations as possible. Any project not reviewed by the HQ Pavement Program Advisor is at risk of being disputed if scoping issues are identified. Provides the framework of policies and procedures for developing State highway improvement projects. Minor projects do not require a PIR and become part of the District’s annual Minor Program. Guidance for preparation of the PIR is located on the Office of Project Planning website's Project Initiation Report (PIR) Guidance page.
In February 2020, the revised California Manual for Setting Speed Limits was released. The specific purpose of this manual is to set forth a uniform procedure for setting speed limits in California. On December 20, 2021 Caltrans announced its new policy for all new transportation projects it funds or oversees to include “complete street” features that provide safe and accessible options for people walking, biking and taking transit. This policy will expand the availability of sustainable transportation options to help meet the state’s climate, health and equity goals. This DIB is not a textbook or a substitute for engineering knowledge, experience or judgment. Many of the instructions given herein are subject to amendment as conditions and experience may warrant.
That can be cost effectively addressed using a combination of pavement strategies. Projects with extensive major pavement rehabilitation (2R or 3R) needs may also utilize some pavement preservation or minor pavement rehabilitation (CAPM) strategies but should follow the guidance in DIB 79. Consult the HQ Pavement Program Advisor and refer to the HDM and DIB 79 for more information. This DIB supplements the highway design guidance and standards provided in the California Department of Transportation Highway Design Manual (HDM). Although design standards are not explicitly stated in this DIB, design standards that are used will be in the same manner as 3R projects (see DIB 79) and as described in Section 2.3 of this DIB.

Pavement preservation primarily consists of nonstructural preventive and corrective maintenance strategies funded under the HM-1 Highway Maintenance Program. The goal of pavement preservation is to maintain existing pavement in generally good condition before more expensive rehabilitation is required. Some pavement engineering strategies for both preservation and minor pavement rehabilitation (CAPM) are similar but are typically applied to segments with different distress extents.
Thus, a performance-based approach is utilized based on performance objectives and assets. This approach together with Departmental goals should result in pavement projects with added features that are feasible, practical, and cost-effective. The work included in a minor pavement rehabilitation (CAPM) anchor project should not propose major facility upgrades but should include all appropriate items of work as discussed in this DIB and within the funding constraints.
Projects with combined extensive satellite asset work greater than half the estimated project cost may not be suitable pavement anchor projects. When minor pavement rehabilitation (CAPM) satellite work is part of another project anchor, limitation of other assets or features described in this DIB are not applicable. See DIB 79 Section 1.4 for information on the appropriate guidance to follow when there are minor and major pavement rehabilitation strategies within the same project limits. Minor pavement rehabilitation (CAPM) projects that are consistent with the guidelines in this DIB do not require design standard decision documentation for existing nonstandard geometric features unless the project scope degrades those features or creates new deviations. The bold and underlined pavement engineering design standards in HDM Chapters 600 through 670 still apply to minor pavement rehabilitation (CAPM) projects.
This new design guidance is a strong statement on the part of the state transportation department that, when roads are designed and improved, consideration must be given to the safety and comfort of road users who are not in cars. A minor pavement rehabilitation (CAPM) individual slab replacement strategy with short service life and low initial cost should be compared to a major pavement rehabilitation (2R or 3R) strategy such as lane replacement, which typically has a 40-year design life. More severe distress conditions may require more robust repair strategies, such as to address localized failures. More extensive distress conditions that exceeds these severity thresholds may require a major pavement rehabilitation project (2R/3R). Pavement preservation strategies may be used on SHOPP projects in combination with more extensive minor (CAPM) or major pavement rehabilitation (2R or 3R) work, such as preserving the inside lanes of multi-lane routes or individual interchange ramps or connectors. However, stand-alone preservation projects on pavement in generally good condition are not funded by the SHOPP or addressed by this DIB.
The Project Development Team guides project development decisions made on this issue. Minor pavement rehabilitation (CAPM) projects may also be appropriate and cost effective on Class 3 roads (see SHSMP) where the facility is beyond the capacity of maintenance preservation strategies to repair. Coordination with the HQ Pavement Program Advisor, District Pavement Program Advisor, and Division of Design (DOD) Project Delivery Coordinator is required if no future major pavement rehabilitation (2R or 3R) upgrades are planned. Otherwise, the project will be considered major pavement rehabilitation (2R or 3R) and is subject to the guidance in DIB 79 and design standard decision documentation for nonstandard features.
Any documentation of design decisions will be in the same manner as defined in HDM Chapter 80. Caltrans recently published the Sixth Edition of its Highway Design Manual, effective March 7, 2014. The Manual serves as the gold standard of best practices in procedures, policy, standards, and guidance in highway design, and is utilized by public agencies in all highway projects that receive state funding. A Project Initiation Document (PID) is used to nominate a major SHOPP project for programming. Depending on the scope of satellite asset work, most minor pavement rehabilitation (CAPM) projects should be Categorically Exempt (CE) projects with little or no environmental impact and work within the existing right of way.
