“…Due to the increased quantities of steel, it has a relatively higher cost. However, compare to other pavement types it can achieve superior long-term performance and cost-effectiveness when compared to other pavement type (Lee et al 2014), with the ability to have service life for over 50 years under severe weather and heavy traffic conditions (Yeon 2015). The most common usage of CRCP design is in an area where load repetitions in the order of tens of millions are expected, such as in corridors where there are dense urban traffic corridors over the service life of the pavement.…”

Continuously reinforced concrete pavement (CRCP) rapidly becomes a common standard in most highway pavement design due to its high performance. Early-age cracks play a crucial role in characterising CRCP's long-term performance, hence crack formations and patterns are of interest in most highway departments. The design parameters of a CRCP are studied in this work as a parametric study on efficient design configuration. Numerical experiments were performed to produce a stress profile induced by crack initiation and long-term traffic load. This work contributes a probabilistic study on crack pattern formation from typical stress profile, including environmental and shrinkage stress, as an insight into predicting the likelihood of crack patterns initiation and propagation along the depth of the concrete slab. Studies also showed transverse steel bar plays a crucial role in determining the location of the crack formation, but a minimal effect in controlling crack width and deflection. A study on the probabilistic model helps pavement design to produce a desirable crack pattern, to perform controlled-cracks that enhance the vertical load transferability of a cracked CRCP.

“…High-early-strength slag cement was used in the overlay concrete to minimize the traffic blocking time and the concrete overlay showed good performance for one year [19]. To achieve the effective repairs of aged and deteriorated concrete pavements, various overlay methods have been developed, and the most effective type of overlay is necessary to analyze the performance of overlay pavement sections [20]. The non-cutting asphalt overlay could reduce the LCC by 18 to 25% when applying the cutting asphalt overlay and the non-cutting asphalt overlay through economic analysis [6].…”

Concrete pavement proportions are increasing in Korean expressways, resulting in increased maintenance cost. The length of degenerate concrete pavements that have exceeded the design life (20 years) was 1150 km in 2015 and 2605 km in 2020 and is expected to rapidly increase. To extend the service life of concrete pavements, life-cycle cost (LCC) analysis was conducted on asphalt and concrete overlays, based on the different maintenance methods. LCC analysis was performed when the shoulder was used and when it was not used between 6000 and 35,000 AADT traffic according to the two-lane and four-lane traffic. During overlay, one lane was completely blocked, and the value per vehicle was converted into the user cost using the Construction Analysis for Pavement Rehabilitation Strategies software, according to whether the shoulder was used to maintain the number of lanes. In addition, LCC analysis was conducted by examining the construction cost and life-cycle according to each overlay method. When the shoulder was used, the total construction cost decreased, owing to the reduction in user cost, indicating that the implementation of the traffic measure of using the road shoulder improves user satisfaction and cost. The asphalt overlay was observed to be more favorable than concrete overlay in terms of the initial total construction cost. However, under a 20-year cycle, the economic efficiency of concrete overlay was higher than that of asphalt overlay. After repairing the deteriorated target sections of concrete pavements, the overlay method (asphalt or concrete) ought to be selected according to the target service life for beneficial economic effect. Concrete overlay was to obtain about 20% or greater LCC effect compared to asphalt overlay, and at least 5% or more additional LCC effect obtained when the shoulder was used.
