Effect of FORTA-FI Fibers on the Rutting Potential, Dynamic Modulus, Flow Number, and Fatigue of Asphalt Concrete

The effect of fiber- reinforcement on asphalt concrete mixes is better explored through laboratory performance testing. Two mixes were evaluated throughout this research. One mix was a standard West Virginia Department of Highways Wearing I, and the other was the Wearing I mix reinforced with FORTA- FIRTM fibers. The testing was done using the Asphalt Pavement Analyzer (APA) and the Asphalt Mixture Performance Tester (AMPT).;First, the rutting potential of the two mixes was determined using the APA. Next, the performance of the two mixes was compared using the AMPT. The tests performed on the AMPT determined the dynamic modulus, flow number, and fatigue characteristics of the two mixes. Dynamic modulus master curves were developed using Bonaquist\u27s MasterSolver Version 2.2 to compare the stiffness of the two mixes. The flow number was evaluated using the Data Smoothing Method and the Francken Model Method to compare the rutting potential of the two mixes. Last, Instrotek\u27s Alpha-Fatigue(TM) software was used to determine the coefficients needed to model the fatigue behavior of the mixes

Daily and quasi-weekly beach profile changes at Monterey, California

Sand heights measured on two beach profiles, supplemented by wave and tide data, were collected on daily and quasi-weekly bases for Del Monte Beach between July 12, 1963, and March 31, 1964. This beach, composed of fine quartz sand, is located in a sheltered indentation where long, low swell predominates. Analysis of the data revealed a dynamic beach characterized by constant daily changes in the lower, active zone, No clear-cut seasonal variation in cut and fill was evident, but large cycles of cut and fill having durations of ten to twenty days occurred irregularly throughout the period. Daily sand-level changes were attributed to constantly changing wave conditions. It was concluded that further research on sand beaches should include wave and sand-level observations taken on a daily basis.http://www.archive.org/details/dailyquasiweekly00koehLieutenant, United States Naval ReserveLieutenant, United States NavyApproved for public release; distribution is unlimited
