PERFORMANCE OF THREE EXPERIMENTAL STRUCTURAL SECTIONS OF EL CENTRO ROAD

This report relates the performance of three experimental structural sections constructed over highly resilient soils during 1959 and 1960 on El Centro Road, 03-Sac-99. Test sections consisted of asphalt concrete over cement treated base, asphalt concrete over asphalt concrete base and asphalt concrete over aggregate base. Structural sections were constructed so that gravel equivalents were approximately equal for the three types of layered systems. The test sections were originally designed to accommodate roughly 10,000,000 EWL's which is equivalent to a 10 year Traffic Index of about 9.0. The performance of the test road after reaching the number of design EWL's was satisfactory for all structural types. However, after 15 years of service the treated base sections showed better performance than the untreated base sections.
