On control characteristics of transverse slope controller paving in asphalt pavement in road curve

Based on the study of control characteristics of curve paving under slope change in asphalt pavement, transverse slope controller is used to control transverse slope. Through analysis of controller step size, initial point of change slope adjustment and slope change adjustment method, the operating parameters are set up, while slope change paving control in curve in practical operation is carried out. The research result shows that, under rational operation parameter and property parameter of controller, output response corresponds to the design value and with high construction precision, under 95% belief degree, error change range is ±0.039%.
