主讲内容简介：

The California pavement maintenance and rehabilitation (M&R) practices are presented based on 35-year as-built data from 1983 to 2017. The top ten treatment strategies, geographical and temporal variation of treated mileage, together with treatment costs and corresponding network condition were identified. It was found that the average annual weighted M&R cost per lane kilometer is about twice as high for concrete pavements when compared with that for asphalt pavements. It was also found that on average, the pavement network was treated 12% of its total lane-kilometers each year, resulting in a 8-year cycle total resurfacing of the entire network. These findings help better prepare maintenance funds and program M&R projects.
