Abstract

The construction of a complementary access road to the top of the dam is to the left of the Tugu dam pedestal. Based on geological studies, it is feared that there is a potential for seepage that passes through the left pedestal through joints, fractures, and fault areas/rock layers below the foundation surface. To anticipate this, the allowable seepage requirement is the lugeon value (Lu) < 3. This study aims to determine the geological conditions and the amount of seepage before and after foundation repairs are carried out using the grouting method. The type of this research is field research, qualitative descriptive because this research tries to collect lugeon population and cement material absorbed into the rock from water pressure test and grouting injection work by grouping each type of hole, pilot hole, primary hole, secondary hole, tertiary hole, and check hole. The study results by taking rock cores found that the constituent rocks were volcanic breccia units and colluvial rocks. Furthermore, a water pressure test before grouting with a water passing value of (k) = 6.62E-05 to 4.73E-04 cm/sec or with a lugeon value (Lu) of 5.07 to 36.21. After repairing the foundation using rim curtain grouting, the seepage that occurs decreases with a water passing value (k) = 1.96E-05 to 3.03E-05 cm/sec or lugeon (Lu) 1.50 to 2.32, so the requirements the target value of Lu < 3 was achieved with the effectiveness in the good category.

Abstract

Road pavement damage is an important thing to pay attention to. Improper planning, increasing traffic volume loads to lack of care and maintenance are factors that cause road damage. Road damage has an impact on the safety of road users. On the Joyoboyo East Kediri road, there are several roads that suffered significant damage. This study aims to design the repair of damage to the East Kediri Joyoboyo road. Repairs are carried out by adding a layer of pavement to the potholes. The component analysis method is used to determine the required pavement thickness. With the component analysis method, the design equivalent cross section will be calculated based on traffic data, as well as soil bearing capacity, regional factors and surface index. So that the pavement thickness index is obtained to determine the required pavement thickness. The result of this research is that the cross equivalent is 116.730, the regional factor value is 0.5 and the Surface Finish Index is 1.5. From the results of these calculations, Nomogram 5 was used and the Pavement Thickness Index value was 5.2. So that the required overlay thickness is 5 cm. These results can be used as a reference in repairing pavement damage on the Joyoboyo Timur Kediri road, so that it can support the safety of road users and facilitate transportation.
