Abstract
|
Cement concrete pavement with a wide range of applications in our country , the skid resistance of traffic safety is critical . Cement concrete pavement skid resistance , objective and accurate evaluation is an important part of road safety analysis and pavement management system , also has a great sense of conservation management . In this paper, our country is widely texturing techniques , the principle of cement concrete pavement and tire friction between a variety of factors affect the performance of cement concrete pavement skid , and studied by laboratory experiments and field tests , a comprehensive analysis of the current cement concrete pavement construction and design specification structure depth of single indicators to evaluate the skid resistance of limitations . Hand push research and development and in the analysis of the advantages, disadvantages and applicability of existing anti-slide detection equipment based on the coefficient of friction test vehicle , indoor and field trials to study the performance of the equipment , the equipment and skid the correlation of the detection device is analyzed. For sanding method proposed road in the groove depth design structure calculation method . Considering various factors , both from the macro - structure and meso constructed of cement concrete pavement skid resistance , determine the structure depth and range of the friction coefficient initially calculated by PIARC model of cement concrete pavement to IFI as required value of the standard value .
