“…Zinc slag filler passing #200 sieve was used to replace a portion of the mineral filler (dolomite limestone) at three different replacement fractions of 35%, 70%, and 100% by volume. These slag contents were selected as in the work of Nabiun and Khabiri [50]. Chemical compositions of the mineral filler and the slag filler were determined using X-ray fluorescence (XRF) spectroscopy.…”

Utilizing the self-healing properties of asphalt materials is a way to improve the service life of asphalt pavements. Enhanced self-healing capabilities can be achieved through mixture modification. Using waste or by-product materials to modify asphalt mixtures can provide further environmental benefits. However, with a given mixture modification method, the resulting materials should be adequately vetted to ensure that enhanced self-healing capability is not attained at the expense of the mixture’s overall performance. This research aims to investigate the feasibility of using zinc slag filler to enhance the self-healing properties of warm mix asphalt (WMA) and evaluates the rutting susceptibility and moisture-resistance of the slag-modified mixtures. To this end, zinc slag filler was used to replace a portion of the mineral filler at different replacement rates in WMA mixtures. Self-healing capabilities of the resulting mixtures were studied under microwave induction heating. The influence of zinc slag modification on asphalt mixture’s characteristics and conventional performance indicators were evaluated by the Texas boiling test, the three-point bending test, and the Kim test (a deformation test). Also, the adhesion between bitumen and aggregate was evaluated using the broken sample from the three-point bending test and digital image analysis. The results of self-healing tests demonstrated that the heat generation capability of the specimens increased with filler replacement rate, such that the specimens with 100% of the mineral filler replaced with slag showed the highest heating performance. Zinc slag filler showed the potential to improve the moisture resistance of WMA by enhancing aggregate–bitumen adhesion and thus reducing stripping. The slag-modified WMA samples exhibited better tensile strength ratio (TSR) and deformation resistance than their non-modified equivalents.

“…Where λ (0) indicates the failure rate of the device if the inspection operation is not performed, in which case by placing equation 15 in equation 14, we will have equation 16.

Among the types of buildings built by humans, roads are one of the most essential buildings (Ziari et al, 2007) and new and recycled materials are used to help the environment (Nabiun & Khabiri, 2016). Increasing social and cultural relations, growth and expansion of economic relations will not be possible without roads, so the existence of roads is an important factor in the progress of human civilization.

Mathematical optimization, also called mathematical programming, is the process by which the best answer (according to a set of criteria) is selected from a set of possible answers to a particular problem. Today, optimization problems are used in all quantitative fields such as computer science, engineering, operations research, economics, and more; one of the engineering disciplines in which optimization is very important is road and transportation engineering. Road repair is one of the most important componentsof pavement management that requires regular road inspection by road specialists. One of the most important measures to prevent failure is maintenance inspection; Assessment of the condition of road surfaces to ensure their performance, while the road still provides maximum safety for existing traffic, should be done to ensure timely and effective repair and reconstruction operations. But exactly when these inspections should take place and when they are effective is an issue that is addressed in this study. The aim of this study is to optimize the frequency of maintenance inspections for a high-traffic suburban road by optimizing the frequency of inspections with a certain degree of reliability; so, the breakage function was considered as a pavement condition index (PCI). The results show that in order to pave the suburban road with high traffic in order to perform the desired pavement with 95% reliability, 218 inspections should be carried out annually (on average once every two days).

Asphalt pavements are damaged by moisture. Strength loss is caused by moisture damage. Anti-stripping agent is used to address this damage in asphalt mixtures. Bitumen modification is also effective method to prevent moisture damage. To this aim, in this study, bitumen was modified by silicon carbide nanotube (SiCNT) in three percentages (1%, 3% and 5%) by weight. After the modification effort was performed, asphalt mixtures were designed according to Superpave TM procedure. Indirect Tensile (IDT) Strength test was employed determining moisture damage in asphalt mixtures modified by SiCNT. As a result, moisture susceptibility of two percentages (3% and 5%) of SiCNT ensured the specification limit.
