Premier is assisting Livingston Parish with an on-going, parish-wide road rehabilitation project, that consist of rehabilitating existing roadways. Premier has been retained to provide subsurface explorations and laboratory testing in order develop recommendations for rehabilitation of the roadways. Our laboratory is performing soil-cement series on every roadway to determine the optimum % cement required to achieve the parish required 150 psi for a stabilized base course. Based on the condition of the existing roadway and the laboratory test results, we are developing an acceptable pavement section based on the ADT and for a 20-year design life using PaveXpress software.
