Preventive maintenance on highway roads

Abstract

Dangerous geological processes such as landslides, mudflows, rockfalls, and bank erosion are observed in many regions of Russia. This paper aims to expand the classification of works on engineering protection of highway sections from hazardous geological processes to reduce the risk of emergencies. The issues of engineering protection of highways are considered, as well as the principles (conditions) formed in the process of their construction, which provide for timely organizational and constructive decisions at the stages of design and subsequent operation. According to the Decree of the Ministry of Transport of the Russian Federation No. 402 dated November 16, 2012, the following classification of works was approved: overhaul, repair of highways, maintenance works of highways. Not only designing new means of engineering protection of highways, but also maintaining the proper functioning of existing ones is relevant for specialists in the field of road construction. A list of recommended measures is designed to ensure reliable and fail-safe operation of retaining walls as well as to analyze the technical condition of landslide protection structures for subsequent measures to prevent emergencies. The present paper indicates a new type of work, i.e. preventive maintenance works, which may involve minor modifications to the retaining wall structure to strengthen it. When they are performed, overhaul of the site is not required.
