At the same time, the maintenance cost of cement concrete is quite high, the health time is long, the traffic interference is serious during maintenance, and it’s difficult to repair once destruction. Thus, a clear understanding of the cement concrete pavement disease and preventive maintenance need to be resolved in today's engineering community. This paper revolves around the maintenance issues of the cement concrete pavement to do research on common diseases and causes of the cement concrete pavement, traffic surveys and performance evaluation, pavement performance prediction, and preventive maintenance measures and the opportunity electi...
