The reasonable estimation of the number of pavement works in the feasibility study stage of highway engineering construction project is one of the basis for the preparation of investment estimation. The selection of pavement structure layer and the calculation of thickness, the calculation of different terrain and pavement area is the main content of highway pavement quantity calculation in mountainous and hilly area. It is of great significance to select the correct calculation method according to different geological conditions. Through 10 engineering cases analysis, the paper analyzes the thickness and area calculation of the pavement structure of the mountain road. It is concluded that the pavement structure layer can be in the form of subbase + base + seal + surface layer. The influence of shoulder, subgrade retaining wall and middle separation zone should be considered in the calculation of pavement area.

Highway engineering quality inspection and evaluation is a key link in highway engineering construction project quality control, and efficient and effective is essential to quality inspection and evaluation. Combined with the quality inspection and assessment standards, a standardized standard library was formed, and the engineering division was improved to achieve refined engineering division and rationalized engineering division. Through the quality assessment and quality rectification, the whole process of assessment is completed, and the QR code visualization technology is used to match the quality inspection table to realize the information management of the quality inspection data and complete the system research and development. Finally, according to the specific engineering application, the efficiency of bridge engineering quality inspection and evaluation is improved, the evaluation data is effectively managed, and the system functions are fully verified.

Reasonable estimation of the project quantity in the feasibility study stage of mountain highway project is one of the basis for the preparation of investment estimation. Combined with the practical work for many years, the content and method of the temporary project, safety measures and other engineering quantity table in feasibility study stage of the highway project in Chongqiu District of mountain are introduced. Taking the calculation of the temporary project of Ningxiang expressway as an example, the basic method of calculation of the maintenance and restoration of the construction access road, the bridge and the original road in mountainous area is analyzed. The author concludes that the influence of geological conditions, topography and original traffic facilities should be considered comprehensively when preparing the temporary engineering quantity table.

Nanyang River channel regulation is one of the major projects for river comprehensive management project in Tianzhen reach of the Nanyang River. According to the geological conditions of ecological restoration, Gabion retaining wall is designed to protect the bed or banks of a stream against erosion. Gabion is made of double twisted hexagonal wire mesh, the thickness of gabion basket and mattress is 50 cm and 30 cm respectively. The slope protection work consists of two parts, the lower part is vertical wall and the upper part is slope wall. The results show that this work can solve the problem of uneven settlement and river scouring, sustain restoration of biodiversity and achieve the harmonious coexistence of humanity and nature.

Nanotechnology can be used for design and construction processes in many areas since nanotechnology generated products have many unique characteristics. These characteristics can significantly fix current construction problems, and may change the requirement and organization of the construction process. This paper reviews the basic concept of nanotechnology, different types of nanomaterial and their manufacturing process as well as the applications of nanotechnology in different fields such as concrete, pavement engineering, construction materials. Use of nanotechnology is found to offer high performing and efficient materials. Specific application areas include water and waste water treatment, construction materials etc. The use of nanotechnology in civil engineering is still in infancy stage. The production methods, pollutions caused to human health, manufacturing difficulties, performance are the issues to be addressed in order to use the nanotechnology in civil engineering.
