Design Data for Rigid Pavements in New Mexico

Historically, New Mexico has been a flexible or asphalt pavement state (98% pavements are made of asphalt concrete). That does not mean that New Mexico should opt out rigid pavements, if they are economically viable options. While a large amount of performance and input data/models were generated and used for New Mexico’s asphalt pavements, the inputs and performances data for rigid pavements in New Mexico are insufficient. This study will develop three of the most important inputs required by the AASHTOWare pavement mechanistic-empirical (M-E) design software in the design of rigid pavement for New Mexico materials, traffic, and climate. Specifically, elastic modulus and/or unconfined compressive strength, modulus of rupture (MOR), and coefficient of thermal expansion (CTE) of various New Mexico concrete mixes will be determined. Several past studies have shown that these three inputs have significant effects on the end design that is pavement thickness and performances. The project will enable New Mexico DOT designers to determine more accurate pavement thickness, because accurate material input values from local materials will be used in the designs. The new pavement M-E design software can be used to design numerous alternatives of flexible and rigid pavements for a given traffic and roadway location.
