One in six roads are still in poor condition despite more potholes being filled in , with more than £12 billion needed to sort out repairs , a new study has revealed . Emergency funding by the Government after last year 's floods helped drive a 33 % increase in pothole repairs , but there has been no reduction in the amount needed to bring the network in England and Wales up to scratch , said a report . The Asphalt Industry Alliance ( AIA ) said £12.16billion was needed to get the local road network back into 'reasonable ' condition , adding that money spent on filling 2.7 million potholes in the past year had been 'wasted ' . The estimated time it would take to clear the backlog of repairs has increased by a year to 13 years , said the report . One in six roads are still in poor condition despite more potholes being filled in , with more than £12 billion needed to sort out repairs , a new study has revealed . The annual survey also found a 'dramatic ' increase in the amount paid in compensation to motorists in England , doubling to more than £20 million outside London . The staffing costs to local authorities for processing claims increased to almost £18 million , equivalent to 225 hours per month per authority , it was found . Alan Mackenzie , chairman of the AIA , said : 'The Government 's emergency funding for pothole and flood repair following last year 's wet winter has clearly contributed to the trends reported in this year 's survey . 'Essentially , the money spent on filling the 2.7 million potholes reported is wasted - it is inefficient and short term in its effectiveness . 'So , while we understand that the Department for Transport is promoting permanent repairs , the point remains that money would be better spent preventing potholes forming in the first place . 'The £6 billion of funding pledged between 2015 and 2021 is welcome , and hopefully will be confirmed by an incoming government . But the truth is that although it sounds like a big investment , it will only be enough for local authorities to tread water and it will do nothing to tackle the backlog or prevent continuing deterioration . ' Peter Box , transport spokesman at the Local Government Association , said : 'Councils fixed more potholes than ever before last year - one every 15 seconds - despite spiralling multi-million pound compensation costs and funding cuts . The estimated time it would take to clear the backlog of repairs has increased by a year to 13 years , a new report claims . 'It is hugely frustrating yet unsurprising that , despite our best efforts , we have not been able to make a dent in the £12 billion roads repair backlog . Patching up our crumbling road network is simply not the answer to tackle the roads crisis we face as a country . 'Councils need billions , not millions , to bring our roads up to scratch . Every mile of motorways and trunk roads will receive £1.4 million funding over the next six years compared with £31,000 per mile for local roads . This makes little sense given the Government 's own traffic projections predict an increase in local traffic of more than 40 % by 2040 . ' Professor Stephen Glaister , director of the RAC Foundation , said : 'Back in 2010 the top transport priority amongst voters was filling in the potholes . Five years later and an RAC Foundation poll shows fixing our roads and pavements remains the public 's number one concern . 'The extra chunks of cash spent on road maintenance over the last parliament have been welcome but with a record number of cars on the road , rising traffic volume and routine resurfacing work taking place only half as frequently as in the 1980s , this issue is unlikely to slip far down the list of things people want ministers to tackle . '
One in millions roads are still in poor shape even after six of potholes fixed . Asphalt Industry Alliance says money spent filling in 2.7million was wasted . A report says that clearing the backlog of repairs could take up to 13 years .
