G5513长张高速公路（益常段）是长（沙）张（家界）高速公路二期工程，位于湖南省益阳市和常德市境内。本项目是湖南“六纵九横三环”中的第三横—浏阳至花垣高速公路的一段，也是实施湖南湘西大开发战略，加强与川、鄂、渝等省市沟通联系，促进湘西北地区经济发展和繁荣的重要通道。 该路面大修工程位于第二标段，设计起点里程为K121+423，设计终点里程K124+349，全长2926m，设计速度100公里/小时，采用双向四车道高速公路标准设计。原路面结构为25cm水泥混凝土面层+18cm半刚性基层+15cm半刚性底基层。由于承担了繁重的交通量，四车道路面均不同程度的出现多处典型的水泥板损坏现象，如不及时处理将会严重影响后期高速公路运行。 经过现场路面检测及专家论证，该段混凝土路面破损较少，基层顶面回弹模量高，结构整体稳定性较好，建议保留旧路面作为新路面基层，采用直接加铺沥青面层的方式进行改造。 旧水泥混凝土路面直接加铺沥青混凝土面层（白改黑）方案，可以有效利用老路面，节省工程造价，但同时又存在以下问题： 一、混凝土面板纵、横缝处理； 二、新老面层间结合力强度； 三、路面防水措施； 四、重交通荷载（路面结构强度）问题。

The two towers that make up the Sunset Cliff complex rise from the top of a slope composed of marl and anthropogenic fill, located just behind the beach. Due to the irregular topography and surface instability, it was decided to reshape the slope's profile through a significant excavation campaign to create different elevation levels. This allowed the architects to meet the owner's requests for recreational spaces at the base of the slope, terraced green areas, swimming pools, access roads, and parking areas at the top. Following the natural terrain orientation, three areas of intervention were defined: North, West, and East, each of which required different earth retention systems to ensure the stability of the remodeled slope.

The Department of Public Works & Highways (DPWH) Second Engineering District of Tarlac Province has approved the improvement and rehabilitation works of the 512 meters long stretch of a concrete-paved provincial highway in La Paz, Tarlac, Philippines. The existing concrete pavement was severely damaged where cracks, potholes, and dilapidated surfaces were observed. A new surfacing course using asphalt was designed by DPWH engineers for the project. However, to avoid total removal of existing concrete pavement while maintaining or ensuring the design life of the new asphalt surface course for the highway, an alternative reinforcing mechanism was required by DPWH engineers.
