2018 Annual Report • 22 a training workshop. The LCCA Excel tool has been delivered that compares initial and maintenance costs of PICP to ICP, asphalt and concrete pavements. This tool is accompanied by a report that provides rationale on accounting for off-site costs not directly related to the PICP. Developing the Excel tool first enables LCCAs of various PICP case studies, which are expected by late-2019. Life-cycle Cost Studies for Interlocking Concrete Pavements This grant funds ten LCCA studies of ICP. This project responds to the ICPI Commercial Technical Promotional Team’s requests for life cycle costs from various geographic regions. Project completion is targeted for early 2020. Permeable Design Pro—Upgrade Software Program to UC Davis Subbase Thickness Tables Method This project upgrades the current software program to include cost-efficient PICP subbase thickness tables developed from full- scale load testing and mechanistic modeling by the University of California Pavement Research Center in 2014. The goal is to reduce the cost of subbases for PICP systems. The program automatically finds the number of days per year rainfall exceeds the 24- hour infiltration depth from a given site soil subgrade, a key design input for determining the subbase thickness. These upgrades will align the program with the 5th Edition of the ICPI PICP manual and the ASCE/ANSI 68-18 PICP standard. Once a beta version is tested, the program will be automatically downloaded to current subscribers via the Internet. Permeable Pavement Road Map Conference—University of California Pavement Research Center The final report provides ways to overcome institutional barriers to wider acceptance of PICP and is available on http://www.ucprc. ucdavis.edu/pdf/UCPRC-RR-2018-01.pdf. The results of the conference breakout sessions are on www.ucprc.ucdavis.edu/permPvmt. This workshop provided ICPI research and development priorities that include the following: 1. Light weight deflectometer research/ application for permeable pavement construction 2. Cataloging state agency positions on PICP for target development 3. Resiliency—PICP and ICP research on enduring floods 4. PICP and underground utilities— Improved, practical guidelines for agencies and utility companies 5. PICP maintenance—Vacuum equipment is improving, and this needs documentation
