“…As various techniques and technologies of road repair are designed to eliminate various defects, the various options for composing repair work will achieve the best improvement of speed. It is recommended to determine the best variant of works from the price-quality trade-off (Rosavtodor 2013;Ahmed, Saeed, Murillo-Hoyos, Labi 2017;Takahashi, Kimura, Moriyama, 2017). One can use the cost of work as the cost indicator, and the quality indicator is the resulting weighted average rate of change of speed Kav.…”

The article deals with the issues of improving the quality of repair and reconstruction of highways design works. The main criterion of assessing the effectiveness of work is the hypothesis that the speed of vehicles depends directly on the condition of the road pavement and the elimination of defects leads to an increase of the traffi c speed. The fi eld research was made to measure the speed of vehicles on road sections before and after repair works. The criteria and factors infl uencing the change in the road speed are determined. The graphic-analytical method is proposed for estimating the service performance of highways based on the prediction of the change of speed.

“…Over the last few years, random parameters modeling has been established as a universally acceptable methodological framework that accounts for unobserved heterogeneity in statistical modeling. This approach has been shown to provide superior statistical fit and forecasting accuracy relative to fixed parameter models (El-Basyouny and Sayed, 2009;Venkataraman et al, 2013;Anastasopoulos, 2016;Ahmed et al, 2017;Zamenian et al, 2017;Semple et al, 2021).…”

“…Expressways have become the main infrastructure for inter-regional transportation due to their advantages, such as fast speed, high e ciency, and large carrying capacity. With economic development and increasing tra c volume, the number of lanes on some expressways can no longer meet the demand for transportation [1][2][3][4][5][6][7]. Highway widening has become one of the e ective solutions.…”

Highway widening has become an effective way to improve the carrying capacity of existing expressways. However, assume that the differential settlement between the new and the old subgrades is not controlled. In that case, it will lead to longitudinal cracks on the pavement, which will seriously affect the safety of vehicles. In this study, the variations of elastic modulus and dynamic elastic modulus of new and old subgrades under traffic load were studied by tests. A hyperbolic model of dynamic elastic modulus increasing with strain is proposed. The numerical calculation model of new and old subgrades under traffic load is established. The deformation characteristics of new and old subgrades without treatment measures and setting up geogrid and geocell are studied. The main conclusions are as follows: (1) with the increase of traffic load and subgrade depth, the elastic modulus changes significantly in the early stage and small in the later stage. (2) Under the condition of no treatment measures, the vertical and horizontal deformation of the subgrade surface show a trend of increasing and then decreasing with the distance from the center line of the subgrade. (3) Setting geogrid and geocell can effectively reduce the differential settlement of the old and new subgrades. (4) The effect of setting geogrid to reduce the differential settlement of old and new subgrades is better than that of setting geogrid.
