Informed Streets Pavement Management Solution

Source: Horrocks' Informed Streets Pavement Management Solution Road maintenance is an essential component of city infrastructure. However, deciding what needs to be fixed and when is often a subject of debate. That's where Horrocks' new pavement management system comes it. Using data-driven analysis, it takes some of the guesswork out of the entire process making road maintenance more cost-effective. This will be an exceptionally great tool for cities like Anchorage, Atlanta, Boulder, Chicago, Indianapolis, Little Rock, Los Angeles, San Francisco, New York, and Phoenix. Informed Streets for Pavement Management Horrocks’ new pavement management system has been dubbed Informed Streets. This is simply because it helps create road maintenance schedules, allowing our clients to maximize their budgets by applying the right treatment to the right road at the right time. This system assesses existing pavement conditions and uses predictive models to develop unique, data-driven management plans that optimize costs and upkeep. These plans are created through the following four stages: 1. Initial Assessment and Survey Horrocks’ mobile LiDAR unit during initial survey In the initial phase of service, Horrocks’ in-house survey crews complete a thorough survey and pavement assessment of the roadways. This is done using a truck-mounted Light Detection and Ranging (LiDAR) unit to assess the pavement by collecting one million survey-grade points every second. Our experts then use this data to develop a baseline for a pavement management plan by providing one of two pavement ratings, depending on our client’s needs: the Pavement Surface Evaluation and Rating (PASER) or Pavement Condition Index (PCI). 2. Data Analysis and Planning Once the pavement rating is complete, an online platform is set up for our client, which includes the Informed Streets3D Viewer. Horrocks’ Informed Streets 3D Viewer integrates GIS systems, LiDAR point clouds, and photography in one robust platform that allows for [...]

3D Finite Element Analysis of a Contiguous Pile Wall

The development site is located on sloping ground approximately 35 m from a motorway cutting. Due to the sloping topography of the site, cut and fill earthworks are to be undertaken to form a level development plateau upon which a large warehouse is to be built. This will require the construction of a circa 400 m long contiguous pile retaining wall to support the ground along the site’s upslope boundary where ground levels will be reduced by up to 8.4 m. Wall Design A plan showing the arrangement of the piles and the 2.0 m wide by 0.8 m deep capping beam is shown in Figure 1. The main 900 mm diameter piles are 17 m long and are staggered in a zigzag arrangement at 0.25 m offsets either side of the capping beam centerline. Interspersed mid-way between the main piles are 600 mm diameter infill piles. The infill piles are located along the capping beam centerline and are 11 m long. Figure 1: Pile and capping beam arrangement Ground Conditions The ground conditions are summarized in Figure 2 which shows a 2D section perpendicular to the wall alignment at the location where the retained height attains its maximum value of 8.4 m. The succession of strata comprises a veneer of clay-rich Glacial Till overlying Coal Measures bedrock. The Coal Measures bedrock is dominated by siltstone and mudstone and has been divided into three [...]
