samples will be obtained for testing. Aggregate base (AB) thickness will be measured at all core locations. A dynamic cone penetrometer may also be advanced at critical core locations to estimate AB and subgrade layer properties. Consultant received pavement pothole data from the City in December 2019 from four locations within the project area of Hesperian Boulevard. Consultant recommends a total of nine core locations be sampled on this street. Therefore, this scope of work includes five additional core locations be sampled by Consultant for the purposes of pavement design on Hesperian Boulevard. Consultant will apply for and obtain a no -fee encroachment permit from the City prior to performing coring work. Preparation of individual traffic control plans for deflection testing is assumed not to be required. 2D) Pavement Design Recommendations: Using the data obtained in tasks 2A — 2C, consultant will perform pavement analysis and design services and develop pavement rehabilitation and reconstruction recommendations for each street section and intersections identified for pedestrian crossing improvements.
