China’S Economy

With the rapid development of China's economy, the construction scale of urban transport is also expanding. Among them, municipal road construction is an important part of urban infrastructure as well as an important guarantee for the development of people's livelihood; it is also an important driving force to promote urban transport system and social life development. The author expounds the importance and basic requirements of urban road designing, and discusses some common problems and countermeasures, hoping to be helpful.

Typical Soil

Continuously increasing municipal renovation and roadbed excavation produced a considerable quantity of solid waste each year such us miscellaneous fill mixed with broken pavement fragments and brickbats, which resulted in a series of urban environment and soil resource issues. Comprehensive recycling technology for soil modification to attain the strength requirements of subgrade fillings from the related road construction codes is necessary and even urgent, since the usual soil replacement is not the economic and environment-friendly method. The field investigation and laboratorial tests hereby had been completed to confirm the application potentials of typical soil specimens selected from different locations. The experimental results indicate some of specimens can be reused as subgrade fillings in road construction immediately and others should be treated by soil amelioration. To further certify the practicality of this recycled technology and broaden its range of application, three typical reutilization and treatment techniques, cold recycling, soil solidification and dynamic consolidation are introduced into engineering projects.

<p>With the rapid development of modern economy, the scale of cities is constantly expanding and the population is constantly growing. Strengthening urban construction has become one of the important work contents of socialist modernization in China. To build a modern city, road construction is the key work of urbanization. Subgrade is the most important construction link in urban road construction and the important foundation of road engineering. In this paper, combined with the specific conditions of urban roads, the construction technology and management measures of urban road subgrade are deeply explored, and perfect construction schemes and management measures are formulated to provide more reliable reference basis for promoting urban development and construction.</p>

Building Demolition

Demolition activity is deeply embedded in the urban system. In recent times, infrastructural development in Nigeria’s major cities has led to increase in road construction activities associated with demolition of hundreds of houses from which millions of tons of Demolition Waste have been generated. However, it is widely reported in many studies globally that demolition debris is such waste that can be re-used. Though, this is not the case in Gombe due to paucity of information on its composition, size and quantities. Hence, the objective of this study is to determine the volumetric composition of generated demolition debris in Gombe City with a view to knowing the potential quantities available for re-use. The study used both qualitative and quantitative design approach. A simple random sampling technique was employed to select 13 roads which were sub-divided in to Lot 1 (8.33km) and Lot 2 (15.04km) and the period of 2011-2014 was considered for the study. Primary data kept by actors and authorities for the compensation assessment which do not refer to demolition debris quantities were used as the bases for extraction of quantities. Handheld (GPS) instrument was used in establishing coordinates; photographs were taken from different locations showing demolition activities taking place and composition of different materials debris. Results revealed that a total of 1,271 structures were evaluated after partially or fully demolished for street widening and/or to pave way for new road construction, in addition a total volume of 129,993.57m3 of Demolished Debris was generated which composed of 10.00% Concrete, 60.30% Sandcrete and 29.69% clay/mud. In conclusion, there exist huge quantities of building demolition debris from street widening and/or new road construction in Gombe city which can be put in to re-use as a component of urban road construction, where properly managed will go a long way to reducing environmental adverse effect due to excessive exploitation for new material.
