TechBrief: LTPP Data Analysis: Validation of Guidelines for k-Value Selection and Concrete Pavement Performance Prediction
Primary Topic: Pavement Maintenance
Description: Concrete pavement performance depends greatly on the support that it receives from the base course and underlying soil layers as well as other support-related factors such as slab curling and warping and slab-base friction. The National Cooperative Highway Research Program (NCHRP) Project 1-30, "Support Under Concrete Pavements" (see Reference 1) developed improved procedures for estimating support design inputs and designing concrete pavements. The new recommended design model gives greatly enhanced capabilities to pavement designers. Concepts for use in future mechanistic design methodology were also developed.
