The present study aimed to ascertain the quality management technologies utilized in the construction of highways in the Sindh province of Pakistan. To accomplish this objective, a comprehensive literature review was conducted to determine the prevailing technologies, including GPS/GIS, BIM, Total Station, Schmidt Hammer, DCP, LWD, GPR, Ultrasonic Pulse Velocity, Remote Sensing, and Vibration sensing devices. A survey questionnaire was formulated based on the identified technologies and circulated among industry professionals. SPSS was utilized to analyze the gathered data and rank the technologies according to their usage frequency. The top three quality management technologies found were GPS/GIS, BIM, and Total Station. The study's findings hold significant implications for enhancing quality management standards in the Sindh construction industry. Future research endeavors may delve into the effectiveness and efficiency of these technologies within the unique regional context.

“…The GeoGauge instrument can evaluate the quality of earthwork projects, and the accuracy of the test results is close to the level of the widely used Light Dynamic Deflectometer. Shubhm Dwivedi [16] shows that GeoGauge detection technology can effectively evaluate the quality of pavement layer during construction and quickly measure and analyze relevant data, so as to carry out quality maintenance on specific sections of expressway. Visvanathan Anusudha [17] tested the compaction quality of subgrade using the Benkelman Beam Deflection (BBD) test, the GeoGauge test, and static plate load tests, and proved that the GeoGauge test results are consistent with other detection methods, which can reflect the compaction quality of the subgrade.…”

GeoGauge is a portable instrument for rapid determination of the stiffness and modulus of compacted soil, which can quickly, safely, and nondestructively evaluate the quality of each compacted layer. In order to deeply study the effectiveness of the detection instrument and equipment used in the soil-rock mixed subgrade, based on the construction project of Beijing-Qinhuangdao Expressway, the influence of water content and compaction degree on the test results and the correlation between GeoGauge detection stiffness and settlement difference were studied and analyzed by indoor model test and field test. Finally, the subgrade compaction uniformity is evaluated according to the measured data of the test section and the predicted value obtained by the ordinary Kriging interpolation method. The results show that: The GeoGauge detection stiffness value shows a trend of first increasing and then decreasing as the water content increases. When the water content is 8%, the detection stiffness value of the earth rock mixture reaches the maximum value. There is a good exponential relationship between the compactness of soil-rock mixture and the stiffness value of GeoGauge detection, and the correlation coefficient is 0.9231, which indicates that the stability of GeoGauge detection results is high. The GeoGauge detection stiffness value increases with the increase of the number of rolling passes. When the number of rolling passes is greater than five, the increase in the detection stiffness of subgrade soil decreases, indicating that the subgrade filler has approached the compaction standard after five passes of rolling. The regression equation between GeoGauge detection stiffness value and settlement difference is established, and the specific index of subgrade stiffness is calculated according to the regression equation when the compactness meets the design conditions, which provides reference for practical engineering.
