Vögele is supporting the nation’s vision of building world class roads by offering unique and extensive range of products.Delhi-Mumbai Expressway is India’s one of the most prestigious expressway project in current time. The highway will start near Gurugram at Sohna and terminate at Mumbai (JNPT). With a total length of 1,353 km, the expressway is divided into 49 packages (31 packages in Delhi-Vadodara section, 13 packages in Vadodara-Mumbai section and 5 packages in Mumbai-JNPT section). The eight-lane expressway is being built under the engineering, procurement and construction (EPC) route and would reduce the distance between the two cities by over 150 km and cut travel time to 13 hours from 24 hours now. Likely to be ready by 2023-24, the project was necessitated because of heavy congestion on the Delhi-Mumbai National Corridor along NH-48 of the Golden Quadrilateral. Passing through Haryana, Rajasthan, Madhya Pradesh, Gujarat and Maharashtra, the Delhi-Mumbai Expressway would also provide easier connectivity to the cities of Jaipur, Kota, Chittorgarh, Indore, Ujjain, Bhopal, Ahmedabad and Vadodara.BackgroundIt is required to pave the width of the road in multiple lanes because paving the full width of the pavement in a project like Delhi – Mumbai Expressway is usually impossible. In this project, a flexible pavement section has base layers such as WMM width of 19.55 meter and bituminous layers vary in width from 19.25 to 18.75 m.Most often, differences in the temperature and mat plasticity causes an improper bonding of the fresh Hot Mix Asphalt with the older Asphalt lane and this subsequently causes the longitudinal joint to possess a significantly lower density than the rest of the pavement. Over time, a longitudinal crack usually occurs between the asphalt mats, permitting the intrusion of water, increasing roughness, and potentially limiting the life of the pavement. While deliberating and adopting the paving methodology in such kind of project, one of the most important factors that comes to mind is the longitudinal joint type and its position. The objective is to have a strongly interlocked joint which provides the same sealing effect as that of other parts in the carriageway to avoid water intrusion into the layer and thus avoid oxidation and raveling of pavement. While there are several conventional methods of joint preparation, making and repair but somehow hot and hot joint proves to be the best among all because of its paving methodology and way to address the base from where generally the problem and defect starts.Paving “Hot to Hot”Paving with two or more pavers in echelon is ideal for an integral bond between asphalt strips. In this paving method, the distance between the pavers is to be kept as short as possible to have a minimum temperature difference between the paved lanes. The first roller following each paver should be of the same size. The rollers start rolling towards the joint from the outer pavement edge inward. Compaction ends approximately 15 cm beside the longitudinal seam on either side. The joint is then the last strip to be compacted by the rollers. This way a tight bond between the strips is obtained. Benefits of Echelon PavingIncreased production per shift Cross-slopes easier to maintainCost-saving on account of repairs of failure of faulty joints.Longitudinal hot joints built by the echelon paving method produce jointless pave-ments.Seamless Product RangeVögele's seamless product range is considered unique in the industry. Whether a service road or a highway, an airfield or a race track, new construction or a rehabilitation job, thick or thin, hot or cold – customers will find the right machine in its product range for every paving task. Its products range from pavers with state-of-the-art screeds to material feeders which are particularly suitable for large-scale job sites and digital solutions for Road Construction 4.0. Vögele is supporting the nation’s vision of building world-class roads by serving its customers with Super 1400 Asphalt pavers (Make in India) and state-of-the-art German technology Asphalt pavers like Super 1800-3 (10 m) and Sper 2100-3 (13 m).The extensive product range of Vögele is divided into two lines: the Classic Line and the Premium Line. The Classic Line is for pavers equipped with the particularly easy-to-use ErgoBasic operating concept. The Premium Line comprises all pavers that feature cutting-edge technology and advanced mechanical engineering. Premium Line products are all equipped with the ErgoPlus 3 operating concept. The varied range of asphalt pavers has paving width ranging from 3.5 m to 18 m in single pass.Meeting end to end requirementsThe company secures its customers’ success with innovative machinery and solutions. Advancements in engineering are all well and good – but for the company, the focus is on turning these advancements into solutions that benefit its customers.In the current scenario, Delhi-Mumbai Expressway itself is one of the biggest examples of the latest technology and high-quality paving by Vögele Asphalt pavers throughout the length. In past, the company had continuously proved high quality results from Wirgen Group machines in Indian road construction whether it is Yamuna Expressway, Agra - Lucknow Expressway, Buddh International circuit, Purvanchal Expressway, Jaipur Ring Road, various airports etc.(Communication by the management of the company)
