“…With the installation of utilities using HDD method within urban and sub-urban areas becoming more famous this method may prone to accidents if it is not carried out properly and its productivity may also affected. [19]. Figure 4, is the illustration of HDD Productivity factors as concluded by Sarireh, consists of four HDD productivity factors namely soil conditions, project conditions, contractor conditions and machine conditions and their sub-factors [20].…”

Horizontal Directional Drilling (HDD) is a trenchless technology provides an installation alternative that offers a lot of benefit compared to traditional open-cut method. It’s called HDD because its steering ability to avoid existing utilities or other obstacles either horizontally, vertically and even pulled back where she got its name. HDD was developed in California in the 1970s and was introduced in Europe in 1986. Since year 1992 up to 2016 there are about 40 thousand unit HDD machine were sold worldwide. Contractors, consultants, municipalities and decision makers are always in difficulties to determine the installation cost and the duration required when using the HDD method due to the presence of many qualitative factors. Understanding the HDD productivity factors will assist the stakeholders to overcome this matter. The aims of this study are to identify the existing HDD productivity factors, identify the factors that affect HDD productivity, identify the current tools that are used by current researcher, and identify the open problems and areas related to HDD productivity for improvement. Systematic Literature Review (SLR) was carried to previous related papers retrieved by a manual search, critically analysed and discussed. Researches regarding HDD productivity conducted by previous researchers were compared and discussed. The studies involved journal articles, conference papers, books, guidelines and etc. Consequently, these previous experiences and models can assist the contractors, consultants, municipalities and decision makers in preparing their costing and scheduling. The lacking factors on HDD productivity factors were highlighted and suggested for futre studies.

“…Then samples of CLA and RVA were tested and compared using ANOVA analysis technique considering the three sources as levels of treatment [28]. ANOVA analysis can be applied successfully to predict differences in means of processes, operations, and products depending on levels of treatment [29] and [30].…”

Round valley aggregate RVA is a natural source of aggregate that is found in Tafi la in Jordan. For current research, RVA from Al-Hasa valley was considered for testing with crushed limestone aggregate (CLA) from Karak and Tafi la sources. 39 samples were collected through the valley at the joint with the lake of Al-Tanour Dam in Tafi la. Samples of RVA and CLA were tested and concrete mix at 15, 20, and 25 MPa. ANOVA analysis was conducted to test means' diff erences in aggregate and concrete properties. Results showed that RVVA has no signifi cant diff erence in means' properties. While RVA has signifi cant diff erences when with CLA from Karak and Tafi la. Results of ANOVA showed that there is a signifi cant diff erence in the properties of fresh and hardened concrete for 15 and 25 MPa concrete grades. While signifi cant diff erence is neglected for 20 MPa concrete grade. Consequently, RVA can be used for concrete mix as CLA.
